A
Few Notes on the PandaTM
Model 10 Loudspeaker.

This loudspeaker has evolved out of well over twenty five years of my design
work with loudspeakers and audio componentry. It carries the pinnacle of
all my ideas and innovations that I have developed in audio and also the
painful removal of many cherished mindsets. The Enclosure is a true point
source alignment ( meaning that the two woofers are located at the quarter
volume points of the internal volume of their enclosure ) One tweeter surrounded
with two woofers. Consisting of two 9" woofers and a single 1" tweeter
and with a first order Butterworth for the Woofer with zoebel network and
a full 3rd order Butterworth with L pad for the Tweeter, the simplicity
of the speakers belies their exceptional performance.

The PandaTM Model 10 Loudspeaker
enclosure is 1600mm high, 400mm wide and 702mm deep and 50mm ( min) thick
. In imperial measurements that's: 63inches high x 16 inches wide
and 28inches deep and 2 inches ( minimum ) thick. The enclosure is
locked by both its internal bracing and numerous metal fasteners and high
strength glue.The front panel is of a Monolithic
construction ( 65mm thick; nearly 3 inches ) and completely made from Plywood;
It sits proud of the other panels and is seamless in all directions minimising
diffraction effects . Each speaker box is centred onto its own dedicated
plywood wooden plinth which is 600mm wide and 900mm deep and 100mm
high ( 24 inches wide x 36 inches deep and 4 inches high ). The internal
volume is over 258 litters ( or just over 9 cubic ft ) and each enclosure
weighs just over 150Kg ( 300lbs+ ).Side panels are a 4 layer varying
density plywood construction, The outer panel face being a thinner
panel of mdf that can be either solid colour or veneered.Rear panel consists of inner
of soft radiate pine and the outer of hardened plywood; total thickness
of the rear panels being 64mm.
Internal wiring is OCC Copper for the woofers
and a single Fine Silver wire for the tweeters. The use of
solder is restricted to attaching the signal wire to the tweeter;
no solder is used in the Woofer // Mid circuit.All crossover connections are
terminated in specially designed and manufactured ( by Bocchino Audio )
junction assemblies known as WireGrubsTM(
All manufactured from Pure Copper, then Silver plated ).All transducers are secured onto
the Monolith with stainless steel bolts secured into custom made
fasteners.The inductors are wound from
pure copper foil and the capacitors are Mundorf Supreme.The Woofers have a specially
designed Transducer Binding post known as W11
WireTailsTM fitted in place of its
standard binding post. The woofers are factory modified to accommodate
the dedicated designed W11
WireTailTM.

Essentially every effort has been
made to secure the transducers as firmly as possible into the enclosure.
No shorcuts on mechanical structure and integrity. The payoff is exceptional
clarity and transparency.

Internal Damping is of a unique
‘air-gap’ buffer design with the majority of the air in the box acting
in synergy with the working transducers. Rear Binding posts are M13MkV
Monopoles® . These, too, are fabricated from Pure Copper;
Silver plated ( No Nickel! Hence no Hall-effect ).

Originally designing loudspeakers for others ( 1983 - 1988 ) I decided
to investigate exactly what makes a loudspeaker transducer feel comfortable
within its working environment. A few very narrow parameters came
out of all this research and seeking loudspeaker transducers with
these parameters proved immensely difficult. There are only two such woofer
transducers that come close to these parameters. Both are exceptional in
their performance but one is better than the other. Only the best went
into the Panda’sTM.Nominally QTS=0.5
and VAS>135 among some of the parameters.

THE SOUND.

What sets these speakers apart
from almost any other loudspeaker is their ability to effortlessly handle
a very broad dynamic range while delivering a very involving musical experience.
All the metaphors of timbral accuracy and image precision are all exceptional
and go without saying. Emotional involvement with the music is very real.
A lot of design has gone into ensuring that transient attack is the fastest
possible while delivering the maximum energy available from the amplifier
with minimal colouration. A greater sense of immediacy than is possible
with a fully soldered path. The listener is immersed into the performance
space where the music was recorded. Seamless and holographic.The Panda Model 10 loudspeaker
is the only loudspeaker in the world that has no solder from the binding
posts all the way to the voice coil. All connections from the binding
post through the crossover through to the transducer chassis are all high
pressure compression connections. No Solder means faster transients and
clearer and crisper definition, not to mention a near perfect noisless
background.

Internal volume is over 258 litters >9 cubic feet.

Weight: 150Kg.

Standard Finish: All panels
are textured matte white with matte black edgings. The
sides can be veneered. There are innumerable veneers available;
please inquire!Or
any plain solid colour.Where more than one colour or
veneer is to be incorporated extra charges apply.

The PandaTM Model 10
Loudspeaker’s are all custom built and
take from 6 - 9 weeks to fabricate and test prior to dispatch and delivery.
The Bocchino Audio direct price per pair is $43,000.00 per pair
(US Dollars) with freight inclusive to most destinations!.
( 8 x Tungsten Mecados
? 8 x FM3 MkIII Pure
Copper Silver plated spades are included in this price). The price
is essentially a wholesale direct price. The PandaTM
Model 10 Loudspeaker is only available
directly from Bocchino Audio. The thoroughness of the bare wire design
( compression connections ), individual testing of all components and correct
electrical and mechanical matching of all elements for the construction
of the PandaTM Model 10 Loudspeaker
are unprecedented in loudspeaker construction.

Warranty is parts only for 3 years.Though I recommend up to a 300
watt amplifier to drive the Panda'sTM a
60watt triode Audio Research Classic 60 copes handsomely.Normal supply is with a
passive crossover.

All PandaTM
Model
10 Loudspeakers are built and tested and tuned by the designer: Carmine
Bocchino. There is no subcontracting of the assembly and testing. There
are no shortcuts.
